Problem Description

Issue

ASE server not showing up outside of LAN, I’ve followed all the troubleshooting I can find and nothing. Firewall has the ports set up right, “ampinstmgr ports” lists them as listening, websites like https://canyouseeme.org/ show the ports as closed. Server launches just fine and can be joined via LAN.

I set up a Terraira server at the same time and it is working perfectly, as well as I had a functioning and connectable-to ASE server running last year.

Reproduction Steps

  • Create an ASE Server
  • Forward required ports
  • Start server and attempt to join via non-LAN
